Abstract (en)
A golf ball includes an inner layer, a cover layer, and a cavity. The cavity includes a conduit connecting the cavity with an exterior of the golf ball. The cavity contains a matrix comprising particles of a first material bound together by a second material. The first material has a density greater than water and the second material is water soluble. Upon prolonged submersion in water, the matrix dissolves allowing the first material particles to exit the cavity. The removal of the mass of the first material particles lowers the density of the golf ball, allowing the golf ball to float to the surface of the water.
